Passenger seats commonly house and carry seat accessories such as cup holders, tray tables, video monitors and controls, among others. These accessories, for example, are often associated with an armrest for use by an adjacent seated passenger,or mounted within a seat back for use by an aft-seated passenger. Accessories may be carried on seat components or integrated into seat frames, coverings or carried on other accessories. Cup holders, for example, are often provided as an extension ofan armrest or as a depression within a surface of a tray table. With regard to cup holder associations with tray tables, such configurations may be advantageous in terms of reducing seat complexity, but disadvantageously require the tray table bedeployed to use the cup holder.

Accordingly, a deployable cup holder associated with a seat that folds into a compact configuration in a dedicated space in the seat is provided herein that overcomes the disadvantages of conventional cup holder designs.

DETAILED DESCRIPTION OF THE EMBODIMENT

An exemplary embodiment of a deployable in-seat cup holder is described herein with reference to the accompanying drawings in which like reference numerals are used to refer to like components. Although an exemplary embodiment is described andshown herein, it should be understood that the exemplary embodiment may be embodied in many different forms and should not be construed as limited to the representative embodiment set forth herein. The exemplary embodiment is provided so that thisdisclosure is both thorough and complete, and fully conveys the scope of the invention and enables one of ordinary skill in the art to make, use and practice the invention.

Referring to the figures, an in-seat cup holder is shown generally throughout the figures at reference numeral 10. The cup holder 10 provided herein is configured to be mounted flush with the surface of a surrounding bezel 12 of a seat back 14or like structure when stowed, and deployed for use as needed by manually actuating a push-to-close type latch for opening/closing the cup holder 10. The cup holder 10 advantageously stows by folding into a compact space defined in the bezel 12 and seatback 14, and opens to a deployed configuration independent of and out of the way of the operation of a tray table assembly 16 and/or monitor of the seat.

Referring to FIGS. 1 and 2, the cup holder 10 is shown in the deployed configuration positioned about one side of the seat back 14 laterally offset from the operating room required by the tray table 16 and/or monitor. As shown, the cup holder10 is mounted to the right side of the seat back 14 at a height about level with the surface of a deployed tray table. It is intended, however, that the cup holder 10 can be located in other positions with regard to the seat. In a preferredconfiguration, the seat bezel 12 may be made symmetrical such that the cup holder 10 can be mounted on either side of the seat back 14 as desired. As shown, the left-side mounting location is unoccupied and covered with a cover 20 that mounts flush withthe surrounding bezel 12. It is envisioned that both the left and right side mounting locations may be utilized at the same time to provide a seat having dual cup holders 10, both of which deploy out of the way of the tray table 16 and/or monitor. Referring specifically to FIG. 2, the cup holder 10 is shown fully deployed and holding a cup 22. Referring specifically to FIG. 3, the cup holder 10 is shown fully stowed and flush with the surrounding bezel 12. The cup holder 10 may display indicia18 thereon, for example a graphic of a beverage, to indicate the identity of the assembly and instruct a scat occupant where to press the master link 26 to actuate the latch 32. The latch 32 and indicia 18 can be aligned to facilitate operation. Theindicia may include operating instructions for actuating the latch 32.

Referring to FIGS. 4-6, the cup holder 10 embodiment shown is a four-bar linkage generally including four rigid bodies, each attached to two others by single joints or pivots to form a closed loop. Specifically, the linkage includes astationary ground link 24, first and second grounded links 26, 28, and a coupler link 30. As used herein, the ground link 24 is also referred to as the "housing," as the ground link 24 houses the first and second grounded links 26, 28 and the couplerlink 30 in their stowed positions. As used herein, the first grounded link 26 is also referred to as the "master link," as the first grounded link 26 engages the push-to-close latch 32 and drives the movement of the second grounded link 28 and thecoupler link 30. The latch 32 is carried on the ground link 24.

The assembly further includes a torsion spring 34 associated with the pivot 36 of the master link 26 and ground link 24 for applying a force on the master link 26 and urging the master link 24 toward the open direction. A damper, such as aviscous hinge damper 38, is associated with the pivot 36 and impedes rapid rotation of the master link 26 relative to the ground link 24, thus preventing overly rapid deployment of the cup holder 10. Pivots of the four links are achieved through hingepins 40. The hinge pin 40 associated with the pivot 36 of the ground link 24 is received through the hinge damper 38, master link 26 and torsion spring 34.

To "open" the linkage, force is applied to the master link 26 by pressing on the link, such as with a fingertip, to actuate the push-to-close latch 32. The resulting release of the master link 26 from the latch 32 causes the force in the woundtorsion spring 34 to rotate the master link 26 outward away from the housing 24, thereby pulling the second grounded link 28 and the coupler link 30 along therewith. With the damper 38 impeding the rapid rotation of the master link 26, rotation of themaster link 26 relative to the housing 24 can be stopped by, for example, contact between the second grounded link 28 and the housing 24. Upon such contact, the torsion spring 34 remains partially wound, and thus keeps the links taught and preloads allthe joints so that they are not loose and do not rattle. As shown in FIG. 5, rotation of the master link 26 relative to the housing 24 results in an angle slightly greater than about 90 degrees therebetween to fully open the cup holder 10.

To "close" the linkage, either master link 26 or coupler link 30 is manipulated by hand, such as by pressing inward in the direction of the seat, to rotate the master link 26 toward the housing 24 to engage a feature 42 defined or carried on theinterior surface of the master link 26 with the latch 32, thus pushing the other linkage members to their starting (i.e., stowed) positions. Latch 32 maintains the engagement of the master link 26 until re-actuated. The master link 26 is housed withinthe housing 24 when the cup holder 10 is closed.

Referring specifically to FIG. 5, the assembled cup holder 10 is shown in the fully deployed configuration. The master link 26 and the coupler link 30 each define a generally arcuate-shaped recessed portion 48 along their lengths forcooperatively conforming to the cylindrical shape of a beverage container, or "cup," to securely hold the cup in the cup holder 10. Although not shown, ground link 24 and second grounded link 28 may also define a generally arcuate-shaped recess. Thecup holder 10 may further include other means for holding the cup, accommodating different sized cups and absorbing shock, such as rubber grips or an elastic diaphragm as known to those skilled in the art.

Referring specifically to FIG. 4, a sectional view taken through the seat back 14 immediately above the master link 26 shows a portion of the cup holder 10 in the fully stowed configuration. The upper flange of the ground link 24 is shownremoved for clarity. In the stowed configuration, the master link 26 is rotated against the housing 24 with the front face thereof flush with the surrounding bezel 12. The second grounded link 28 and the coupler link 30 are arranged generally parallelto one another and a portion of the second grounded link 28 is received within the larger coupler 30 to further enhance compactness and save space. The cup holder 10 folds to a compact, generally linear configuration that when stowed does not requiresignificantly more depth than the seat bezel 12. The cup holder can be secured to the seat or seat bezel by securing the ground link 24 to the seat frame or bezel 12 using any suitable fastener or fastening technique.

The linkage of the cup holder 10 can be constructed from any material, with preferable materials including rigid plastics and like materials that can be colored to match the appearance of the surrounding bezel 12, for example.

While an in-seat cup holder has been described with reference to a specific embodiment and examples, it is envisioned that various details of the invention may be changed without departing from the scope of the invention. Furthermore, theforegoing description of the exemplary embodiment of the invention and best mode for practicing the invention are provided for the purpose of illustration only and not for the purpose of limitation.
